Retails on the company's site and Amazon for $60. Massdrop's MSRP is accurate. Not knowing the shipping, I would suggest that this is worth it over Amazon (for once), as they don't offer Prime, selling for $65 + 4.99 shipping.

This edition of the game appears to have both the cards and board, but the cards alone can be found on their website for $25 (http://maybe.capital/buy-the-board-game/).

The price, however, seems to have gone up to $60 at some point since November 2017, when it was promoted at $42 (https://www.thememo.com/2017/11/23/maybe-capital-board-game-vc-fundraising-silicon-valley-sexism-in-tech/). Either way, you're paying pretty much what it's suggested to be worth.

As to the difference between card & board game editions, here's quote from the game's maker:

"Cards Only Game: Just Cards, No Board
Full Version: Has Board and Cards and Player Pieces.
The Card Game is a simpler version and the board game has 4 additional elements. "
